You sure must have heard about cats having nive (or sometimes seven) lives,sometime or the other...It is a myth in many cultures.The myth is attributed to the natural suppleness and swiftness that cats exhibit in life-threatening situations. The fact that falling cats often land on their feet (because of an inbuilt automatic twisting reaction,and are able to twist their bodies around to land on their feet),though they can still be injured or killed by a high fall,lends more credence to the myth...
